Spoke too soon sizing is still off.

those are the first results.

i spend some time tweaking the probe sensitiviy, i noticed that the effector was tilting over on a probe, so increasing the sensitivity to 15 seems to have helped it. the parts are more in size now. i ran the 7 factor and it decided the arms were all the same length but needed to be as follows:

M665 L293.761:293.761:293.761 R136.460 H323.451 B134.0 X0.096 Y0.131 Z0.000
M666 X0.978 Y0.004 Z-0.983 A0.00 B0.00

sizing seems to be improved now

@dc42 sorry I should have mentioned that the parts are too small. I'll reduce the arm length like the 7 factor did.

here is what the log said: 6 factor original steps per mm and original arm length.

this was the final override

M666 X0.941 Y0.019 Z-0.960 A0.00 B0.00

please let me know how to proceed

@t3p3tony ooops sorry! totally missunderstood. i'll run g32 a few times and report back

@t3p3tony

sure! what data do you need? i posted the results above before i changed the arm length. here are the images

so i changed to 7 factor with 16 points.

this is what it wrote to the override file

M665 L286.069:286.069:286.069 R133.041 H321.956 B134.0 X0.220 Y0.287 Z0.000

considering the arms are supposed to be 291.06 and this is what seemecnc use on their printers with duets, any ideas what could be causing this?

yes, here is what i found.

i am updating this value and running the test again.

the printer was printing within the expected size range with the Rambo board, and when i disabled the probe and probe manually with a paper the error seems to go away. the issue seems to be with the probe trigger. it is much better with the smart effector vs the bltouch i removed before.

i have also run the bed probe 6 times and this is what i got:

thanks for the help.

im using the ball arms from seemecnc, they are injection molded and i just checked they are all the same length. i measured them a few different ways and got a number of 291.5mm but its hard to measure the center of a circle and i don't have calibers long enough. seemecnc think the arms are 291.06mm

here is a pic of the printer. i am not using the pcb adapters.

ok do im still chasing issues with my delta and im sure its due to the auto calibration not being able or over correcting my setup.

parts are not sized correctly and if i am interpreting it correctly the printer is moving in a concave arc (higher in the middle)

the bed level compensation seems to show this too. any ideas how i fix this?

where do i start?

printer is a rostock mk2 with injection molded cheap skates, ball cup arms, smart effector, e3d volcano , maker 713 metal effector plate for smart extruder.

everything is tight and seems to be working ok its printing well just not to size

thanks
